To all whom it may concern.'

Be it known that I, ALFRED BREDENBERG, a citizen of the United States,and a resident of Champlain, Clinton county, New York, have inventedceitain new and useful Improvements in Bookbinding-Machines, .of whichthe following is a specification.

The present invention relates inoie especially to book-binding machinesand involves a transferring mechanism adapted to assist or renderautomatic certain operations of such binding machines; although the in-1 veiition might be equally useful in various other kinds of machines.'

The invention has for an object to provide a means for successivelytransferring a series of objects, such as signature-groups,

^ from the delivery of a gathering mechanism into justified positionwithin a series of clamps, for such binding or other operations as areto be performed upon the same; the gathering and binding mechanismsheilig thus operatively associated into a single book making machine;and other and more specific objects will appear hereinafter inthefollowing description or Will be obvious therefrom. The termsigiiature-gro-iip shall be used herein in al representative sense asincluding any analogous object consisting of assembled componentsdesigned finally to constitute a book or analogo-us article.

The invention consists in the novel parts, constructions, contrivancesand combinations hereinafter sliown or described.

The accompanying drawings referred to inthe following description andfoiniing a part hereof, illustrate one embodiment of the presentinvention, the same seiving in connect-ion with the description toexplain the principles of the invention.

ln the drawings, Figure 1 is a front elevation` partly in section ofparts of a book binding machine, including a transferring mechanismembodying the present improvements. Fig. 9. is a right-hand elevationpartly in section taken substantially on the plane 2-2 of Fig. 1. Fig. 8is a plan view of the mechanism seen-in Figs. 1 and 2. Fig. 4 is a frontdetail view of one of the coiitrivances shown in Figs. l, 2 and 3; Fig.5 being a similar view of the same in a different stage of operation;and Fig. 6 being a right-hand view thereof.

The .present invention involves a book binding machine including 1ncombination a signature gathering mechanism, a bindinggatheringmechanism to the position (upright) in which it is moved into the clamp.

yThe term clamp is used in a sense to include equivalents.

More specifically looked at the invention includes the followingfeatures:

The transferring mechanism hereof comprises a distinct part which may betermed a holding member or holder, which is adapted to have the objects(signature-groups) fed into it one at a t-ime, combined with a movingmember for moving or lifting each successive object from the holder intoengagement with a clamp or the like.

According to another feature of the invention the holder is of suchcharacter as to receive each successive signature-group or lotherobjectflatwise and thereafter swing or tip upward into substantiallyupright position preparatory to a vertical (preferably ascending)movement of the object into a clamp or the like.

According to still another feature a mov- =ing or lifting member iscontemplated which engages with the object inthe holder and moves bodilyfrom the holder (upwardly or downwardly) toward the clamp, carrying theobject thereto. According to still another feature is contemplated a.contrivance for shifting the olojects to the holder, comprising an armor finger which reaches out for each successive object and draws it intopro-per position in lthe holder; this contrivance shown as cooperatingWith the delivery of a gathering mechanism. According to still another`feature is contemplated a certain. clamp-operating con- ,trivance whichserves to open and close a -clamp in harmony with the operations of theother parts of the mechanism.

As further features of the present invendicated as the object handled byt tion are justifying or registering stops serving to insure theaccurate positioning of each objectl so that when it has been engagedinl the clamp for any desired subsequent operations, it will occupy theprecise necesment that is illustrated in the drawings hereof, in'which asignature-grou Z is iniie mechanism. Some of the main portions of themachine, as to which per se no claim of novelty is herein directed, willfirst be described, and thereafter the novel mechanism illustrating thepresent invention will be set forth.' The machine has a frame A carriedon a base A, and certain specific frame parts that coperate with thetransferring mechanism will be hereinafter described in connection withthe latter. .In the upper part of the frame is an upper guide B andlower guide B 'shown in the form of channels adapted to receive betweenthem and guide carriers of any known design comprising clamps C, C',intended to hold a book, signature-group or other object to be treated.The said guides and carrier constitute a convenient and well-known meansof successively presenting a series of signature-groups to the variousinstrumentalities comprised in a book binding machine; and forconvenience there may be an extended series o-f carriers connected in atrain and intended to move intermittently along the guides B, B', whichlnay take the form of an endless track, as clearly seen in Fig. 3, sothat each carrier or clamp on completing a cycle of operations willstand at position ready to repeat. The

guide is indicated in Fig. 3 as having a.

straight st-retch o-n either side of the machine and a curved connectingportion at either end. The arrow?) indicates the direction of travel ofthe carriers; and several carriers are indicated in dotted lines inaddition to the one which is in cooperation with the transferringmechanism forming the particular subject of this invention. Thus C2indicates a carrier-whose clamp has been opened to release a book thathas completed its treatment; C3 and C4 indicate the succeeding positionsin which the clamp has closed; The clamp C, C', shown in cop-.

eration with the present invention is indicated in open position. Vhen'aclamp has l been opened it is preferably closed by means of springssufficiently powerful to hold the object firmly within the clamp duringthe book binding, covering or other operations. which may be performed.Connected to the outer clamp part C for this purpose are a pair of rodsor stems 0, c which extend through apertures in the innerA clamp partand are encompassed by helical springs c2 having considerable length soas to secure substantial uniformity of pressure for varying thicknessesof objects. Atthe inner ends of stems c, 0 are heads c3, c3 adapted tobe pressed upon by a means which will be hereinafter described, for thepurpose of sliding the stems outwardly and opening up the clamp againstthe resistance of the springs o2 which subsequently close the clamp.

Portions of a gathering machine or mechanism are shown as illustrativeof various mechanisms in conjunction with which the presentI inventionmight be employed, and such gathering mechanism will not be described infull detail as it. is the subjectof protection and description inanother application filed by me April 28, 1911, Serial No. 623,872. Agathering mechanism is one which from supplies of signatures or the likeselects one of each variety and assembles them into a signature group,the actual assemblage being performed if desired upon a support orcarrier along which the'assembling books are caused to travel. Such asupport D is indicated in Fig. 1, it being slotted and having atraveling chain or sprocket (Z projecting through such slot so as tostand above the support surface. The sprocket chain Z passes around asprocket wheel Z2 mounted on a shaft which has another sprocket wheelengaged by a second sprocket chain Z3 which in turn engages sprocketwheel (Z4 mounted on the same shaft X as the bevel gear wheelhereinafter to be referred to, from which the sprocket chain (l obtainsits motion. A flange (Z5 along the lower edge of the inclined .carrieror support D is contacted by each assembled book and keeps the same fromfalling from the support. Each pin (Z on reaching the sprocket wheel (Z2passes downwardly out of the slot, and the accumulated signatures orassembled book in fro-nt of such pin is thereby delivered at the leftend of the support D, which left end may therefore be designated adelivery support D.

Portions of the mechanism to which the present improvements moreparticularly redelivery support D before referred to, that is, so as tohold the assembled signatures substantially flat-wise; and as seen infull lines in Fig. 2, the holder E and consequently the delivery supportare not exactly horizontal but substantially inclined for a purposewhich is only incidental to the present invention, and insufficient inextent to change its character from what it would be if normallystrictly horizont-al. The holder E is seen in Fig. l in dotted lines andit is clearly seen in Fig. 3 in plan view to consist of a platenactually shown as divided by a slot e into a main portion e and asmaller portion e2, the slot being inclined at least at its upper endand serving a purpose which will hereinafter appear. The objects havingto be fed upon the holder E from right to left, it is provided at itsleft edge with a flange or stop e3 preventing over travel of the objectand serving to adjust it into 'proper registration for further actionupon it. The holder E has a back plate or support e4 whose tting will behereinafter described. At the inner lower edge of the holder isindicated a flange or stop e5 preventing the objects sliding off theinclined holder, and flange being in line with and forming substantiallya continuation of flange d5 of the delivery support D.

' Havingthus identified the holder E, reference will now be made inorder to thefollowing, namely: a cont-rivance which serves to reach outto the delivery support and draw each object upon the holder; a means ofeffecting certain movements of the holder E for cooperation with themeans hereinafter in this paragraph mentioned; a means Ifor moving eachobject from the holder E into an open clamp; a means for` causing eachobject upon entering the clamp to move laterally or in its own plane forpurposes of adjustment to certain stops; and a means for causing,` theopening and closing o f a clamp in harmony with the otherinstrumentalities.

. The reaching out contrivance comprises a swinging arm F carrying ahand F on which is a nger f, these parts so located that the nger iscapable of extending up through the slot of the delivery support Dbehind a signature-group or book for drawing the same forwardly on tothe holder E. The arm F is secured to a sleeve f2 loose upon a studf'which is fixed to the frame of the machine as indicated in dottedlines j in Figg, and is incapable" of rotation. The hand F is pivoted atf4 to the arms upper end so as'to be able to swing to a slight extent topermit the finger f to 'be moved out of and into the slot of thedelivery support.

To swing the arm F may be employed a link f5 connected at one end tosuch arm and at the other end to a lever f6 turning about a fixed pivotf7. The link f5 is provided with a spring f8 tending to pull it and thearm F to the right, Figs. 1, 4 and 5, and the lever f6 is provided witha roller f adapted to engage the surface of a cam flo mounted upon ashaft X. By the rotation of said shaft the lever f and arm F areoscillated to and from the positions seen in Figs. 4 and 5 respectively,and during such oscillation the movements of hand F and finger f arecontrolled as follows. Mounted on the xed stud f3 and capable of turningthereon, is a sleeve f which is provided with a tightening device f bywhich any desired amount of friction between the sleeve and the shaftmay be secured. The friction sleeve is held 'in place on the stud by twocollars f2", f2 on outst-roke to swing downwardly out of such position.The connections between friction sleeve fu and the finger f comprise anarm fw secured to the sleeve f and having pivoted to its extremity ashort link f whose other end is connected to one arm f15 of a two-armlever in the nature of a bell crank, having a rotating stud f1projecting from arm F, and whose other arm f in turn has pivoted to it along link fm extending upwardly to where it is adjustably pivoted atf1.9 to the hand F that carries at its extremity the finger Fig. 4represents the parts as having just reached the .end of the instroke,and they are about to return out- Wardly o-r to the right.` The frictionof sleeve fn temporarily renders it substantially stationary with studf3 so that through link f the movement Vto the right of arm F effects aslight oscillation of the bell crank fw, f, and a pulling down of thelink f18 and consequently a lowering of the finger f out of the slot ofthedelivery support. A stop f22 on arm F limits the bell cranks rotationin this direction, its rotation in the opposite direction being limitedin a manner that will hereinafter appear. The swing'ofthe bell crank isinsufficient to permit the friction sleeve and arm fla to remainstationary throughout the entire swing of arm F, and consequently at acertaln point the sleeve f commences to overcome reaching itsbook-engaging position. The finger f is not formed directly on the handF but as seen in Fig. 6 is substantially offset therefrom, the hand andfinger being connected by a roller f2s; this arrangementpermitting thefinger to enter the slot of the delivery support, but preventing thehand from entering it, and the roller f2s serves as a stop coming intocontact with the edge of the slottedsupport or a track f thereunder, andpreventing the finger rising above the position seen in full lines inFig. 4 and in dotted lines in Fig. 5. As soon as the roller f23 has beenlifted with the finger sufficiently to contact the delivery support, thefriction sleeve as before commences to revolve with respect to the studf3. On the instroke the roller f23 will slide along immediately ybeneaththe delivery support and maintain the finger f throughout suchstroke inproper book-engaging position.

By the described operations of the reaching-out contrivance a book orother object on the delivery support is reached out for and slidinwardly from said support into the holder which as before stated isnormally in line with the support, and the inmotion is continued untilthe book is brought into contact with the stop e3 of the holder, atwhich time the book is in position to permit the operations of theinstrumentalities hereinafter to be described.

The shaft X above referred vto may be considered a secondary shaft, themain shaft X being preferably the one to which power is applied fordriving the mechanism of the present invention; and said shaft X may beconsidered as a single machine part taking the form of a shaft andhaving connections to the several instrumentalities 'referred to for thepurpose of driving all of them in harmony with each other, or in themanner herein specified. The shaft X may receive motion from shaft Xthrough a bevel gear :u on the latter engaging a bevel gear on theformer.

There will now be described the means for swinging the holder E from theposition in which it receives a book to the position in which the bookis removed from it. Such swinging is substantially from the fiatwise toan upright positionl and such swinging correspondingly swings the book,enabling thc latter to be then vertically moved from the holder into avertically arranged clamp or the like. In employing the words vertical,upright, etc., it is not done in an absolute sense, since approximateverticalness would obviously suffice and in any case it.

is the relative arrangement which is important. Fig. 2 shows the holderE in its substantially fiatwise position in full lines, and in dottedlines swung to a substantially upright position, in which latterposition in order to hold the book or signatures the `holder is broughtface to face with an upright retaining part G, said retaining partcoperatmg withthe holder when the latter is first swung upwardly, andthereafter during the vertical movement of the book out of engagementwith the holder and into engagement with a clamp. Said retaining part ispreferably a fixed part and may constitute a portion of a frame member gwhich is extended downwardly and is secured to the base A at its lowerportion and to the guide B at its upper portion. The retaining part orwall G is slotted at g2 and g', such slots being generally vertical buttheir upper parts at least being inclined for a purpose that willhereinafter appear. The frame part g of which the retaining wall Gconstitutes a part, is of substantial construction, flanged wheredesirable, and it forms the base or support for certain movable parts aswillbe hereinafter described.

For 'swinging the holder E an axle z, may be employed, to which theholder E and its back plate e4 are suitably secured, and said axle atone end is provided with an arm h extending to where at its extremity itis pivoted to a link h2, which link at its other end is yoked at h3 andprovided within said yoke with a roller h4 bearing upon and actuated bya cam h5 mounted upon and rotating with the main shaft X; and saidroller and yoke being guided through a swinging arm h6 pivoted at theupper end of a short f standard if and having an extension 71,8 actedupon by a spring it in such manner as to tend to retain the roller h4 incontact with the cam 71,5. The cam z is of such contour as to causefirst the up-swinging of the holder E, followed by a pause sufficientlylong to permit the removal of the book, followed by a down-swingingmovement and a pause sufficiently long to enable a new book to bereceived on the holder.

The moving or lifting member which vertically shifts the book or otherobject from the holder E to a clamp, may for convenience consist of aplurality of members such as the twin members J, J, each having anoutwardly projecting stud j, and working in harmony so as to constitutesubstantially a single contrivance. Each member J in addition to theprojection j on which the book rests edgewise, may comprise a slide j',said slide conveniently located to the inside of'retaining wall G, andthe projection y' extending on the outside thereof beneath 4the holder`E; there being a connection between the slide and projection, suchconnection consisting of a pin y'2 extending through the slot g or g2 inthe retaining wall, and an upright link ja supporting the projection atits upper end in such a way as to permit lateral play of the latter sothat it may accommodate itself to the varying positions of the slot as50 tween holder E land wall G directly into the -correspondingly formededges of the slide j. Thus by sliding the slide j upwardly anddownwardly the studs y' are carried upwardly and downwardly in acorresponding manner and additionally are given lateral movementsaccording to the inclined por? tions of slots g', g2.

To actuate the slides j', j2 to move upwardly and downwardly a link jmay be pivoted to the rear of each slide and extended to where at itsother end it is pivoted within the yoked end je' of a long lever j?,there being two identical levers j? as seen in Fig. 8, and each havingits far end pivoted at js to a fixed part of the machine. A pair oflinks j pivotedw to intermediate portions of the respective levers j?,j?, extend downwardly and are connected by a rod j, to which rod isconnected the lever jl", whose other end is pivoted at j to the centralrib g3 of the frame part g. A pair of opposed rollers'j12 on lever jl"bear upon a corresponding pair of cams jm mounted on the same shaft Xthat carries cam h5, said cams j having such contour as to cause upwardand downward movements of roller l7'12 with pauses between so that thelever j? and in consequence the slides j', y", will likewise moveupwardly and downwardly with pauses at each end of their stroke.

The same shaft X operating the mechanism just described and also causingthe swinging of the holder E, they will work in harmony, the' cams beingso timed that 5 afterthe holder` has swung upwardly, the lifter thencomes into play and from Fig.

2 it will be clearly seen that the studs j must push upwardly edgewiseagainst the books and force them from thespace beopen clamps C, C',which is the function of the lifter.

following mechanism may conveniently be employed. Reference has alreadybeen made to slots g, g2 in the retaining wall G, and to thefact that afollower j connected to the stud y' engages such slots. It has also ibeen made to appear that the holder E has a"slot e, this receiving theouter extremity of one of the studs j, the other stud j being in vaposition beyond the holder E and not requiring a corresponding slot. Nowall of the slots g', g2, e, while generallyvertical, are inclined atleast at their upper ends as shown, and the inclinations of all of theslots are the same in position and extent. The result is that the studsy' on nearing the end of their upstroke and at a time when the book issubstantially in position within the clamp, are caused to be swunglaterally or to the right in Figs. l and 3 tending to carry the bookmore than a sufiicient distance in that direction to insure the contactof the book with the stem c of the clamp', said stem forming aconvenient stop for securing the proper adjustment of the book.

For opening and closing the clamp C, C, the following contrivancemayconveniently be employed in coperation with the previously describedinstrumentalities: A part or bar K is of such shape and so located as tocontact with the inner ends of the spring encircled stems c, c', towhich the movable clamp member C is secured.. Bar K causes the openingof the clamp by pushing-upon said stems and causes the closing bywithdrawing to permit the springs c2-to operate. The rod K is shownattached to the upper end of an arm k which actuates it to move towardand from the clamp, and to steady the same the rod lc is secured at theside of the bar opposite to the clamp extending to -where it slideswithin slide-way or sleeve 7a2 pivoted between fixed frame parts 7c3,k3. Arm 7c is actuated from a shaft 7c* extending parallel to shaft X;and said shaft if* at another point on its length is provided with asecond arm h5 extending downwardly to where at its lower end is a rollerlo@ engaging and rolling upon the surface of a cam la" secured to'shaftX.. Said cam 7N is of a conf tour to cause the bar K to push the stemsc, c and thereby open the clamprfollowedby a pause, after which theclamp is permitted to close, followed by a second pause to giveopportunity for another and empty clamp to j be carried by the bindingmechanism into position for receiving the succeeding signature-group.

The preferred operation of the above described parts will be as follows:Assuming a signature group to have been delivered on the support D bythe gathering mechanism and assuming an empty clamp to have beenpresented in the position sho-wn7 the first action of the transfermechanism willbe the reaching out by the arm and finger F, f, engagingthe book on thedelivery support and drawing it inward until it restsupon the swinging holder E, the book Z 'being seen infthis position inFig. 2. Theholder then swings from the vsubstantially atwise positionshown to an upright position, its flange e5 keeping the signatures inlplace and the opposed retaining wall G serv-ing in cooperation with theholder E to keep each ceeding clanip lifter J then comes into play, itsstuds j contacting directly against the lower edge of thesignature-group, and as said lifter rises the group is forced upwardlybetween holder and retaining wall, while the studs j are guided by theslots g', g2 in the retaining wall. The clamp C, C having previouslybeen opened by the opener or bar K and said clamp standing uprightdirectly above the space between the holder and retaining wall, thegroup is thereby caused to pass directly into the clamp between itswalls C, C; and the upward movement is continued until the group reachesthe proper predetermined height. During `the rise of the group the studsj engaging the inclined portions of slots g", g2, are caused to movelaterally, swinging about their links js and thereby bodily carrying thegroup of signatures laterally or edgewise toward the right, Fig. l,until said group comes in `contact with the ystem c of the clampsuchstem serving as a stop insuring the accurate positioning of the group.The clamp opener K then withdraws causing the closing of the clamp bythe action of the springs 02. This substan-` tially completes one cycleof operations, following which the lifter J and holder E return to theiroriginal posit-ions prior to the transfer of a succeedingsignature-group from the gatherer delivery to the neXt sucy of thebinding mechanism. The different cams referred to are so timed astobring about the above described operations in the order named.

It will be seen that by' reason of the construction above shown landdescribed, a transfer mechanism is provided which answers the objectsand affords the aditantages of the invention as hereinbefore set forth;and other advantages will be appar-v ent to those skilled in the art.

It is to be understood that the invention in its broader aspects is notlimitedto the precise construction shown nor to any particularconstruction by which the invention -has been or may be carried intoeffect since many changes may be made in the details of the partswithout departing from'the main principles of the invention and withoutsacrificing its chief advantages.
